Background modeling is currently used to detect moving objects in video acquired from static cameras. Numerous statistical methods have been developed over the recent years. The aim of this paper is firstly to provide an extended and updated survey of the recent researches and patents which concern statistical background modeling and secondly to achieve a comparative evaluation. For this, we firstly classified the statis Read More

Radio Resource Management (RRM) is especially crucial for wireless multimedia networking, where: (i) wireless resources are scarce and precious; (ii) multimedia applications impose a strong Quality of Service (QoS) support. In this context, Mobile Network Operators (MNO) have to find a trade-off between optimizing wireless resources (in terms of radio utilization), while ensuring QoS and hence increasing user satisfaction (or Q Read More

Rapid advances in Wireless Sensor Networks (WSNs) indicate that they are becoming increasingly complex. Consequently users and applications are becoming more demanding. Due to unique characteristics of WSNs, like small dimensions and limited resources and capabilities, Quality of Service (QoS) is imposed as one of the key factors of WSNs. In this paper, we surveyed two main approaches for QoS provisioning in WS Read More

Distance-based k-nearest-neighbors (KNN) retrieval is usually adopted to find nearest neighbors for the target case in case-based reasoning (CBR). However, in practical application, the similarity metrics calculated by this means often estimate the actual situation with bias because different features have different units and magnitudes. To avoid this problem, method of feature normalization is usually employed before the im Read More

In a parallel system, nodes communicate with each other by exchanging messages. Different topologies exist for arranging processors in a network based on the architecture of the network; or based on the fact that a network is a multiprocessor or multi computer network. A honeycomb network is considered as a multiprocessor / multi-computer interconnection network where each node represents a processor/computer Read More
